IMPROVEMENT lN CHAMBER-CLOSETS.

Specification forming part of Letters Patent N o. l 89,802, dated April17,1877 application filed February 7, 1877.

To all whom it may concern Be it known that I, ELIHU SMITH, of the cityand county of Albany, State of New York, have invented certain new anduseful Improvements in Chamber-Closets, which improvements are set forthin the following specification, and the accompanying drawings, in whichFigure 1 represents a perspective view of a chair with my improvedcloset attached. Fig. 2 is a sectional elevation of the same. Fig. 3 isa plan View. Fig. 4 is a cross-sectional view of the heating-chamber andventilating-flue.

The object of my invention is to furnish the chamber-closet with a meansfor carrying off all odors or foul gases from the said closet, andrender the apparatus odorless, so that no ofiensive smell or odor mayescape into the room, but be carried away through conduits or fines, tooutside the building.

In the drawings,Arepresents a chair, stool, or other equivalent device,for the accommodation of an individual. B is a tight chamber, providedwith adoor, a, having damper doors or registers a, for admission of airto the said chamber, the door B itselt serving to permit entrance to thechamber for the introduction or withdrawal of the vessel 0, forreceiving the feces. The walls of chamber B are made of metal, or linedwith metal, or other material that may not absorb or retain odors, asglass, porcelain, par-afline paper, sheet metal, or enameled metal. Thelower side of seat A of the chair A, forming the top of the saidchamber, is also lined with a similar material forthe same purpose.

Made central in the seat A is the orifice D, which communicates with thechamber B, and-with the feces-vessel O beneath. E is a sliding covermade slightly concave in its up per surface, closing the orifice D, andis capa ble of being slid out to one side, as shown by full and dottedlines in Fig. 3, to produce a passage for said orifice to the vessel 0,and to close the same when the said sliding cover is slid inward, asindicated by dotted lines in the same figure. 1

Leading from the chamber B rearward is the flue F, which flue leads tothe exit G intended to enter a flue, pipe, or conduit made in the wallsof the room, or placed in the room and communicating to the outside ofthe building through any suitable flue or opening. Made below the rearportion of the said flue, or at the side of the same, is theheatingchamber H, which chamber is provided with a door, h, for accessto the same. A stimulating-plate, c, separates the said chamber from theflue F, and operates as a radiating piece when a lamp or gas flame ismade to heat the said plate. J is a lamp occupying the heating-chamber,theflame ofwhich warms or heats plate 6, and rarefies the, air in therear of flue F, over or at the side of said heating-chamber, so as toproduce a draft from chamber B to the flue or conduit K, as indicated byarrows in Fig. 2. It should be understood that the rear portion of flueF is on a plain'higher than the top surface of seat A, by which none ofthe gases or odors will be permitted to escape into the room through theorifice D. A draft-opening, d, is made in the cover E, as shown in Fig.1, through which air may be drawn.

It may be readily seen that,.as the exit 'G is at a point above theplain of the orifice D, the foul gases or odors may not escape into theroom, but will be drawn away into the flue or pipe K, in a positivemanner. It may also be seen that, when the stimulating-plate e is warmedor heated from the fire in the heating-chamber H, the air in the flue Fmay become rarefied, and thereby stimulate the draft of the apparatus,and that the room in which the chair stands may be ventilated by openingthe draft-dampers c in front, to permit the air of the room to pass intochamber B, and thence through the flue F to the flue or conduit K.

A guard, L, is also provided at the front of orifice D, to direct theurine discharged into vessel 0. The said guard is removable, and may bereadily detached or applied, as may be required.

Having described my invention, what I claim, and desire to secure byLetters Paten t, is-

y The combination of the seat A, chamber B, flue F, and heating-chamberH, as and for the purpose herein specified.
